Well my experiment with coating two piece grip panels to look just like ivory worked out great for my Remy.
However; doing the same on one piece 1851 grips was an entirely different story.
With the two piece Remy grips it was easy to simply lay each grip panel on a flat surface and spray it with the hard epoxy, extremely white paint, let that dry, then followup with a coat of clear polyurethane which covered the extremely white epoxy paint with a slightly yellowish coating giving the grips a very realistic ivory color look. So for two piece grips it worked out great for me.
But it's just as important to post about failures as it is successes, so that others can learn by our failures and not make the same mistakes. So here's one.....
The one piece grip on my 1851 Marshall was a real pain to mask inside. So many contours and edges. But I did that with masking tape anyway. (I hung the one piece grips up with wire so I could spray all around them rather than just doing one side at a time). I had sanded down the factory imperfections in my Marshall grips and gave them a light coat of grey auto primer. Then sanded that with 600 grit wet/dry sandpaper.
Then I sprayed on the epoxy paint and let that dry for several days.
One thing about this epoxy paint. It takes at least a week for even a moderate coat to fully cure....even hanging outside in the hot summer Florida sun. Then I would sand it with 220 followed by 600 grit sandpaper. But I kept getting imperfections in the paint from my sanding. What was happening was the top of the paint was dry, but as I sanded it....it would still not be fully cured underneath....and it would "wrinkle" the paint.
Then I would have to wait a few more days letting it hang up in the sun to cure THAT exposed wrinkled portion until I could sand the "wrinkles" out.
This went on and on with me sanding out wrinkles and then respraying the one piece grip. Until....I had built up WAY TOO MUCH paint on the grips. I couldn't oven bake the grips either because the epoxy paint doesn't seem to like the oven and wrinkled when I tried drying it in the oven. (I have a shop oven so wifey doesn't get mad at me for using her kitchen oven
.)
Finally I had sanded the epoxy smooth and finally had the grip ready for the final topcoat of epoxy paint to cover up my final sanding marks. Then I sprayed it one final time with the white hard epoxy paint. And let that dry for several days hanging outside in the hot sun. Everything seemed to be working out and all I needed to do next was very lightly 600 grit sand the grips and then spray them with clear polyurethane to get that ivory look.
I lightly sanded them and sprayed them with the clear polyurethane. But the surface of my grips were so smooth by now that the clear polyurethane didn't adhere that well believe it or not....and ran to the edges and collected there in lines that would have to be sanded out. RATS!
So I let that dry and sanded the clear poly down with 220 grit followed by 600 grit. This was hopefully the last time I would have to sand I thought.
Well....as I was sanding the overrun clear poly and epoxy paint that had built up so thick on the grips (about 1/32's thick) suddenly a fingerpad sized section of the paint on the grips just wrinkled and went inward.
That ruined everything. There was no way I could fix that without stripping EVERYTHING off the grip and starting completely over! DOUBLE RATS!
I had used too much epoxy and not let it dry sufficiently between coats. The top shell was cured but underneath it was still not completely cured and pressure from sanding moved the paint underneath the top cured shell and ruined everything. Chiefly because it takes so long for the epoxy to cure and I had used too much even though I knew better because this same thing has happened to me before on other projects. I was counting on the epoxy being cured enough and it wasn't.
So I immersed the grip in a container of brake fluid (not having any paint stripper immediately on hand) and let it soak for several hours. Then I fingernail scrapped off all the paint. Finally when I had it down to most of the paint off, I used drywall sanding sheets that go on a reciprocal sander that have little square holes all over the sheet. That way the gummy paint would not load up the paper and make it slick like it would if I used regular sandpaper.
I got all the paint off and yes I could have started all over again recoating it, but with brake fluid in the wood that might preclude paint from adhering correctly, I decided to just keep them walnut. They came out fine and look even better than they did with their raised imperfections from the factory that I had sanded out so they are smooth now. Plus I had sanded out the clear coating they put on them at the factory and now they are very smooth walnut with linseed oil rubbed into them. I like them better than how they originally came. Here's a few pics of them AFTER I had sanded the raised factory imperfections out, and AFTER I removed all the paint off them from my failed project, and after I rubbed linseed oil into them....
So no harm done and my grips are back to their wooden look but even better since I sanded out the raised factory imperfections and got the clear coat off and linseed oil rubbed finished them.
So ended my experiment in epoxy painting ONE PIECE 1851 grips.
What I (and we) learned from this is that two piece grip panels work very well for epoxy coating and then clear (yellowish) polyurethane coating to realistically imitate ivory. But ONE PIECE grips are a bit more of a pain.
Two piece panels lay right on a flat surface and require no masking and are easy to paint. The one piece grips require a lot of inside the grip masking and have so many contours to mask and that create other problems that they are not worth trying to do the same thing with. Two piece=yes, one piece=no.
I did find a site online where you can send them a tracing of your grips and they will send you a three piece kit with two grip panels and a spacer where the panels are just slightly oversize to your tracings so you can sand them to an exact fit and the spacer goes between the two grip panels and you glue it to the back side of the panels once properly positioned. They cost approx $38.00 and you can pay $14.00 extra and have a selection of medallions put in them if you desire. If I decide I just HAVE to have ivory colored grips on my 1851 Marshall, (and I probably will)....I will send in my tracing and order a set from here, probably with the big texas star medallion in them since I really liked that medallion out of all their medallion choices....

So feel free to do the coating I described in this thread on TWO piece grip panels, but I wouldn't personally try it again on one piece grips. Too much masking, too many contours, and although the paint and sandpaper are cheap, the time it takes for ONE PIECE grips isn't worth it. I wish now I had just ordered a $38.00 set with the $14.00 medallions and not have wasted my time. BUT....my two piece Remy grips DID turn out just fine and I wouldn't hesitate to do a TWO PIECE set again.....just not another ONE PIECE set.
Learn from my experience without having to go through what I went through over the past several weeks trying to get this one piece grip ivory coated.
All for now.
